History

Four were bought by the Swedish Coastal Artillery as 10.5 cm kanon m/27s. They were later upgraded to m/34 standard as m/27-34s. They were transferred to the field artillery in 1942.

Dutch guns were known as Stuk van 10-veld. The Dutch appear to have bought guns with both 40 and 42 caliber barrel lengths. Captured weapons were designated by the Wehrmacht as the 10.5 cm Kanone 335(h).

Hungary licence built an improved version of this gun and used them as the 10.5 cm 31.M ágyú on the Eastern Front during World War II.

Design

The gun was designed for motor traction with spoked steel wheels with rubber rims. The spades were removed and placed onto the trail legs for transport.
